PAPERFMATERIAL CONTAINER.

Application filed December 30, 1915.

To all whom it may concern.-

Be it known that I, Gnonon L. SCALES, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Paperhiaterial Containers, of which. the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to a paper-mater al container, and besides possessing rlgidity and durability as prerequisite of this character or" container, it possesses all of the characteristics essentiai for a perfect san tary receptacle. The most important samtary characteristic is that of a protected and clean pouring edge and this feature is embodied in my invention by a novel form of closure, which fits over the pouring edges of the container and maintains the same in a sanitary condition from the producer of the contents of the container to the consumer of the contents, irrespective of the nature of the liquid container.

From a manufacturing standpoint, the container possesses those characteristics which lend ease to manufacture of the container, facilitate ling and closing the contamer, and permit of the container being readily openedj/ J The above and other advantages will appear as the nature of my invention is better understood, and reference will now be had to the drawing, wherein Figure 1 is a vertical sectional View of a paper-material container embodying char acteristics of my invention;

Fig. 2 is a cross sectional View of a closure for the container, and

Fig. 3 is a side elevation of a portion of the container.

In the drawings, 1 denotes a paper-material body of any cross sectional area, said body having an end thereof permanently closed, as at 2. The opposite end of the body provides a pouring edge 8, and my invention particularly relates to the closing of the open end of the body and the protection of the pouring edge 3 thereof.

Fitted over the pouring edge dot the body 1 is a closure made of a paper-material and this closure has an annular outer depending flange 5 and an annular inner flange 6 or less depth than the annular flange 5, said flanges being disposed to coiiperate i h the c o ure form g an annula Specification of Letters Patent.

groove 7 to receive the pouring edge 3 of the bodyl. The closure 4 has a central annular depressed portion 8 provided with a con centric opening 9 having for its walls an inwardly projecting flange or. seat 10 adapted to receive an ordinary paper-material cap or seal, such as commonly used for closing milk bottles.

The outer depending flange 5 of the closure 4. has diametrically opposed depending gummed tabs or tongues 12 adapted to be secured to the Walls of the body 1 to hold the closure upon said body.

In the construction of the body 1 and the closure 4 a very durable paper-material is used which can be rendered impervious and non-absorptive by paralfin, gelatin, or a similar material, applied in a thin coat by dipping or otherwise. The closure 4 may plies of paper-material pressed or otherwise shaped as above defined, and as illustrated, the closure is made of two plies with the innermost ply forming a stiffening or reinforcing member for the outer ply. The innermost ply includes the annular depending flange 6, also another depending flange 13 which adds rigidity to the depressed portion 8 of the closure. These two plies when glued or otherwise connected together and incased in paraflin present practically a homogeneous mass and the closure can be easily mounted upon the pouring edge of the body 1 and secured thereto by the tabs or tongues 12. Paraffin may be also used to seal the closure 4; relative to the body 1 and to remove the closure, it is only necessary to cut the tabs or tongues 12 and give the closure 4: a slight twist to release the same relative to the body 1.

The opening 9 permits of the container being filled and the producer of the contents of the container can easily place the cap 11 in position to close the container. The cap is sprung into the depressed portion of the closure and frictionally held therein. In some instances it may be hermetically Sealed upon the flange or seat 10 by parailin, and instead of removing the cap 11 to obtain the contents of the container, the closure 4 is bodily removed, sanitary pouring edge for the contents of the container.

By reference to that the closure is a modification of Fig. 1, it will be observed comparatively flat and as this construction, there is thus providing a clean and shown in Fig. 2 e closure similar in con struction but substantially frusto-conicel shape in elevation, such closure tending to shed liquid or any matter that may lodge thereon contiguous to the side walls of the container.

VVhet ll claim is A closure for :i paper-material container, comprising papcvnmteriel formed with outer and inner annulmdepending flanges providing a groove adapted to engage over the edge of a container with the outer flange of greater depth than the inner flange, said closure having a, central depressed portion on to t .top of the closure, and tales secured; to the worsens providing an opening concentric with the 15 container and e seat at the marginal edges of said opening to receive a fiat ca cliepted to be sax-1mg into the opening of tlie closure e seat to lie in a plene well below the outer flange of said. closure and eolapteal for attachment to the Wells of the container.

In testimony whereof I afiix my signature in presence of two witnesses.
